Abstract
A touch input device is configured to apply an information input method and system for use with a portable terminal. In the information input method and system, when a touch against the touch input device is not released, voltage generated in a resistive overlay touch screen is changed by the touch input device and various functions are performed according to the voltage change.
Claims20
A method for inputting information using a touch input device in an information input system comprising a portable terminal including a resistive overlay touch screen and the touch input device, the method comprising:
- checking whether a voltage is changed when a touch is generated while the touch input device is being touched;
- estimating a voltage change corresponding to a difference between the changed voltage and a voltage generated by the touch;
- and
- performing a function set according to the estimated voltage change.
An information input system using a touch input device comprising:
- a touch input device configured to change a voltage generated on a resistive overlay touch screen, the voltage generated by a touching of the touch input device;
- and
- a portable terminal comprising the resistive overlay touch screen, the portable terminal configured to estimate a voltage change corresponding to a difference between a voltage changed by the touch input device and the voltage generated by the touch, and wherein the portable terminal performs a set function according to the estimated voltage change.
A portable terminal comprising:
- a resistive overlay touch screen;
- and
- a controller configured to estimate a voltage change corresponding to a difference between a voltage changed by a touch input device and the voltage generated by a touch of the touch input device, and perform a set function according to the estimated voltage change.
